Ignore Attribute Unavailable - Warning in Xcode4

I use a lot of “custom identifiers” for toolbar items, which is good in Xcode4, but when I create a project I get a bunch of warnings:

Attribute unavailable. User identifiers in interface designer versions up to 3.2

Is there a way to ignore these warnings in Xcode4? This is pretty messy when I look for "real" warnings and errors.

Click on your xib file. In the properties you will see the following section:

Where he says "Development", change this to Interface Builder 3.2 and you will no longer receive these warnings.

UPDATE for users of iOS Xcode: In iOS 4.3 - IB is built into the IDE, and on the right after selecting the xib file some icons will appear, the first icon is called "File Inspector" (looks like a page with a fold), where (see below).

I am running Xcode 4.2 build 4C199.

  • Click on the xib file,
  • on the right, click Utilities

  • Click File Inspector. As tony.stack said in the "BuilderDocument Interface" section
    set Deployment = "Project SDK version"
    set Development = "xcode 4.2"

    Even if you are using xcode 4.2, Development is set to the default value of 4.1, so you will get this warning.

Have you tried looking in the Document Information window in the Builder interface? You can install supported versions there.
